We have not and have not authorized anyone to provide you with different information, and we do not take any responsibility for any other information that others may give you.

    TABLE OF CONTENTS

    SPECIAL NOTE ABOUT FORWARD-LOOKING STATEMENTS
    In addition to historical information, some of the information in this prospectus, any accompanying prospectus supplement or free writing prospectus, and the documents we have incorporated by reference contain or will contain certain references to future expectations and other forward-looking statements and information relating to our financial condition, results of operations and business. These statements include, among others:
    •
    statements about our anticipated exploration results, cost and feasibility of production, production estimates, receipt of permits or other regulatory or government approvals and plans for the development of our properties;
    •
    statements regarding strategic alternatives that we are evaluating, or may evaluate in the future, in connection with our business;
    •
    statements concerning the benefits or outcomes that we expect will result from our business activities and certain transactions that we contemplate or have completed, such as receipt of proceeds, increased revenues, decreased expenses and avoided expenses and expenditures; and
    •
    statements of our expectations, beliefs, future plans and strategies, anticipated developments and other matters that are not historical facts.
    These statements may be made expressly in this document or may be incorporated by reference to other documents that we will file with the SEC. All statements other than statements of historical facts included or incorporated by reference in this prospectus, any accompanying prospectus supplement or free writing prospectus may constitute forward-looking statements which may use specific words, including but not limited to “may,” “will,” “should,” “expects,” “forecast,” “project,” “intend,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of those words and other comparable words. Forward-looking statements and information are based upon several estimates and assumptions that, while considered reasonable by management, they are inherently subject to significant business, economic and competitive uncertainties, risks and contingencies, and there can be no assurance that such statements and information will prove to be accurate. Therefore, actual results and future events could differ materially from those anticipated in such statements and information.
    Included among the forward-looking statements and information that we may provide is production guidance. From time to time the Company provides guidance on operations, based on stand-alone budgets for each operating mine. In developing the mine production portion of the budget, we evaluate several factors and assumptions, which include, but are not limited to:
    •
    gold and silver price forecasts;
    •
    average gold and silver grade mined, using a resource model;
    •
    average grade processed by the crushing facility (Gold Bar) or milling facility (San José mine and Fox Complex);
    •
    expected tonnes moved and strip ratios;
    •
    available stockpile material (grades, tonnes, and accessibility);
    •
    estimates of in process inventory (either on the leach pad or plant for the El Gallo mine and Gold Bar, or in the mill facility for the San José mine and the Black Fox mine);
    •
    estimated leach recovery rates and leach cycle times (the El Gallo mine and Gold Bar);
    •
    estimated mill recovery rates (San José mine and Fox Complex);
    •
    dilution of material processed;
    •
    internal and contractor equipment and labor availability; and
    •
    seasonal weather patterns.
    Actual production results are sensitive to variances in any of the key factors and assumptions noted above. As a result, we frequently evaluate and reconcile actual results to budgeted results to determine if key assumptions and estimates require modification. Any changes will, in turn, influence production guidance.

    THE COMPANY
    This summary below highlights selected information about our company. This summary is not complete and does not contain all of the information that may be important to you. For a more complete understanding of us you should read carefully this entire prospectus, including the “Risk Factors” section and the other documents we refer to and incorporate by reference. In particular, we incorporate important business and financial information in this prospectus by reference.
    McEwen Mining Inc. (the “Company”) is a gold and silver mining production and exploration company with an advanced copper development project, focused on the Americas. We were incorporated under the laws of the state of Colorado in 1979 as US Gold Corp. In September 2011, US Gold Corp. acquired Minera Andes Inc., and was renamed McEwen Mining Inc. We own 100% of the Froome mine and Stock mill in Ontario, Canada, 100% of the Gold Bar mine in Nevada, 100% of the Fenix Project in Sinaloa, Mexico, 48.3% interest in McEwen Copper Inc., the owner of the Los Azules copper project (“Los Azules”) in San Juan, Argentina, and a 49% interest in MSC, the owner and operator of the San José mine in Santa Cruz, Argentina. In addition to the above, we hold interests in advanced-stage and exploration-stage projects in the United States, Canada, Mexico, and Argentina.
    On October 6, 2017, we acquired certain assets and liabilities from Primero Mining Corp., a British Columbia corporation (“Primero”). The assets we acquired from Primero (collectively, the “Assets”) include the Black Fox Complex, an operating underground precious metal mine, associated mining claims and equipment located in the Township of Black River-Matheson, Ontario, Canada and the Grey Fox and Froome projects, exploration properties located near the Black Fox Complex. All of the Black Fox Complex, the Grey Fox and Froome projects are located in the historic Timmins mining district in Ontario where we already owned a number of exploration properties. We paid a purchase price of $35 million for the Assets, which included adjustments for the replacement of certain cash collateral securing reclamation obligations, and in addition, we assumed certain liabilities, including accounts payable and environmental liabilities.
    Our commencement of Canadian operations in 2017 was facilitated by the acquisition of Lexam VG Gold Inc. (“Lexam”) in April 2017, followed by the acquisition of the Black Fox Property and Stock Property from Primero Mining Corp. in October 2017. These two acquisitions provided us with an operating mine, mill, and significant land interests in the historic Timmins mining district of Ontario (collectively, the “Fox Complex”). On September 19, 2021, our currently operating Froome mine, located within the Black Fox Property, reached commercial production.
    In the United States, construction began on our 100% owned Gold Bar mine in Nevada in 2017. The Gold Bar mine poured its first gold ingot on February 16, 2019, and achieved commercial production on May 23, 2019. Current production is from our Pick, Ridge and Gold Bar South (“GBS”) deposits.
    At the El Gallo mine in Sinaloa, Mexico, mining and crushing activities ceased during the second quarter of 2018, with production activities since that time limited to residual leaching up to the third quarter of 2022. The Company is currently reviewing reprocessing heap leach material at the El Gallo mine (“HLM”) as well as new silver processing operations (“El Gallo Silver”) in the immediate vicinity as part of its Fenix Project.
    In July 2021, we announced the creation of McEwen Copper Inc. (“McEwen Copper”), through which we hold an indirect interest in Los Azules, located in the province of San Juan, Argentina, and the Elder Creek exploration property, located in Nevada. From 2021 to 2023, we completed a total of $267.3 million in private placement offerings by McEwen Copper, which included a $40 million investment by an affiliate of our Executive Chairman and Chief Owner, Robert McEwen in McEwen Copper.
    Our objective is to increase shareholder value through the exploration for and economic extraction of gold, silver, and other valuable minerals. Other than McEwen Copper’s operations of the San José mine and the Los Azules copper project, both located in Argentina, we generally conduct our activities as the sole operator, but we may enter into strategic arrangements with other companies through joint venture or similar agreements. We hold our mineral property interests and operate our business through various subsidiary companies.

We expect the amount and type of consideration we will offer and the other specific terms of any acquisition will be determined by negotiations with the owners or controlling persons of the businesses, assets or securities to be acquired after taking into account the current and anticipated future value of such businesses, assets, properties or securities, along with all other relevant factors.
    The shares of our common stock to be issued in connection with any acquisition made pursuant to this prospectus will be registered under the Securities Act and will be freely transferable under the Securities Act, except for shares of our common stock issued to any person who is deemed to be an “affiliate” of ours following the consummation of the applicable acquisition.
    When we issue common stock under the registration statement we may provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with additional information described under the heading “Where You Can Find More Information.”

    DESCRIPTION OF COMMON STOCK
    We are authorized to issue up to 200,000,000 shares of common stock, no par value and 10,000,000 shares of preferred stock, no par value. As of August 21, 2024, there were a total of 51,085,515 shares of our common stock issued and outstanding and no shares of preferred stock issued and outstanding.
    The following discussion summarizes the rights and privileges of our outstanding common stock and is qualified by reference to the relevant provisions of the laws of the State of Colorado and our Amended and Restated Articles of Incorporation (our “Articles of Incorporation”) and Bylaws which have been filed with the SEC and are incorporated by reference into the registration statement of which this prospectus is a part.
    The holders of McEwen common stock are entitled to one vote for each share held of record and the holders of any fractional share are entitled to a corresponding fractional vote on all matters submitted to a vote of McEwen’s shareholders, including the election of directors. Cumulative voting for directors is not permitted. Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of McEwen common stock are entitled to receive ratably those dividends, if any, as may be declared by the McEwen Board out of legally available funds. Upon McEwen’s liquidation, dissolution or winding up, the holders of McEwen common stock will be entitled to share ratably in the net assets legally available for distribution to shareholders after the payment of all of debt and other liabilities of McEwen, subject to the prior rights of any preferred stock then outstanding. Holders of McEwen common stock have no preemptive or conversion rights or other subscription rights and there are no redemption or sinking funds provisions applicable to McEwen common stock. There are no restrictions on the alienability of McEwen common stock and there are no provisions discriminating against any existing or prospective holder of McEwen common stock as a result of such holder owning a substantial amount of its securities. All outstanding shares of McEwen common stock are fully paid and non-assessable.
    Under the terms of McEwen’s articles of incorporation, the McEwen Board is authorized to direct McEwen to issue shares of preferred stock in one or more series without shareholder approval. The McEwen Board has the discretion to determine the designation and number of shares of any series of preferred stock, the voting powers, if any, of the shares of such series of preferred stock, and the relative, participating, optional or other rights and preferences of the shares of any series of preferred stock, including, without limitation, dividend rights, dividend rates, terms of redemption, redemption prices, conversion rights, and liquidation preferences. The powers, preferences and relative, participating, optional and other special rights of each series of preferred stock, and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding.
    The ability of the McEwen Board, without action from McEwen shareholders, to issue undesignated preferred stock with voting or other rights could impede the success of any attempt to effect a change in control of McEwen. These provisions may also have the effect of deferring hostile takeovers or delaying changes in control or management of McEwen. The McEwen Board has determined to consider the adoption of a shareholder rights, or “poison pill,” plan because it believes that such a plan may be in the best interests of McEwen and its shareholders. At this time, the McEwen Board has not approved the adoption of any plan but is in the exploratory stage of doing so. If the McEwen Board determines to adopt such a plan, the availability of preferred stock would be useful to the implementation of such a plan. The McEwen Board’s determination to consider the adoption of such a plan is not in response to or in anticipation of any pending or threatened take-over bid, nor a desire to deter any particular take-over bid. The McEwen Board is not currently aware of any hostile takeover attempts directed at McEwen. The McEwen Board is considering such a plan to ensure that McEwen’s shareholders are treated fairly in the event any such bid to acquire control of McEwen is made. A rights plan may also be useful in preserving the net operating losses that McEwen currently has available to offset any future income.

    TABLE OF CONTENTS

    PLAN OF DISTRIBUTION
    The common stock covered by this prospectus is available for use in connection with acquisitions by us of other businesses, assets, properties or securities.
    The amount and type of consideration we will offer and the other specific terms of any acquisition will be determined by negotiations with the owners or controlling persons of the businesses, assets, properties or securities to be acquired. We may structure business acquisitions in a variety of ways, including acquiring stock, other equity interests or assets or properties of the acquired business or merging the acquired business with us or one of our subsidiaries. The consideration for any business acquisitions may consist of shares of our common stock or a combination of common stock, cash, notes, assumption of liabilities or other consideration. The shares of common stock issued to the owners of the businesses, assets, properties or securities to be acquired normally are valued at a price reasonably related to the market value of such common stock either at the time an agreement is reached regarding the terms of the acquisition or upon delivery of the shares.
    This prospectus may be supplemented to furnish the information necessary for a particular negotiated transaction, and the registration statement of which this prospectus is a part will be amended or supplemented, where appropriate, to supply information concerning an acquisition.
    All expenses of this registration will be paid by us. It is not expected that underwriting discounts or commissions will be paid by us in connection with issuances of shares of common stock under this prospectus. However, finders' or similar fees may be paid from time to time in connection with specific acquisitions, and the fees may be paid through the issuance of common stock covered by this prospectus. Any person receiving a fee may be deemed to be an underwriter within the meaning of the Securities Act. We may also pay certain financial advisory or similar fees or reimburse certain expenses of investment banking firms that advise us from time to time generally or regarding a specific acquisition.

    PART II
    INFORMATION NOT REQUIRED IN PROSPECTUS
    ITEM 20.
    INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    The Colorado Business Corporation Act provides that the articles of incorporation of a Colorado corporation may contain a provision eliminating or limiting, subject to certain exceptions, the personal liability of a director to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director. The articles of incorporation of McEwen contain such a provision.
    Under the Colorado Business Corporation Act, a Colorado corporation may generally indemnify a person made a party to a proceeding because the person is or was a director or officer of the corporation against any obligation incurred with respect to the proceeding to pay a judgment, settlement, penalty, fine or reasonable expenses incurred in the proceeding if the director or officer acted in good faith and certain other conditions are satisfied. The Colorado Business Corporation Act also authorizes a Colorado corporation to pay for or reimburse the reasonable expenses incurred by a director or officer in defending a proceeding in advance of the final disposition of the proceeding if certain requirements are satisfied. McEwen’s articles of incorporation provides that McEwen may indemnify each director, officer and any employee or agent of the corporation, his heirs, executors and administrators, against expenses reasonably incurred or any amounts paid by him in connection with any action, suit or proceeding to which he may be made a party by reason of his being or having been a director, officer, employee or agent of the corporation to the full extent permitted by the Colorado Act as now existing or as hereafter amended.

    UNDERTAKINGS.
    (a)
    The undersigned Registrant hereby undertakes:
    (1)
    To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
    (i)
    To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
    (ii)
    To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
    (iii)
    To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;
    (2)
    That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
    (3)
    To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
    (4)
    That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
    (i)
    Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
    (ii)
    Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the
    II-3

    TABLE OF CONTENTS

    prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
    (5)
    That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
    (i)
    Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
    (ii)
    Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
    (iii)
    The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
    (iv)
    Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
    (b)
    The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
    (c)
    The undersigned Registrant hereby undertakes the following:
    (1)
    That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.
    (2)
    That every prospectus (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
    (d)
    Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission
    II-4

    TABLE OF CONTENTS

    such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
    (e)
    The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this Form S-4 within one business day of receipt of such request, and to send the incorporated documents by first-class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the Registration Statement through the date of responding to the request.
    (f)
    The undersigned Registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the Registration Statement when it became effective.
